Valve may not ever release sales figures for any games that sell on Steam, but that doesn't mean the company doesn't like to boast about sales from other sources - especially when games sell as well as Valve's Left 4 Dead
Speaking at the Game Developers Conference in America today, Valve revealed that the four player co-op zombie shooter Left 4 Dead
had sold more than 2.5 million copies...at retail alone
In other words, that's not counting the sales that come from Valve's own Steam platform, so the real sales figures are going to be much, much higher than that. Like really big; just remember how much Steam sales can jump when a discount hits
and then bear in mind the recent Left 4 Dead
The figures do cover both PC and Xbox 360 releases, according to ShackNews
, but the developer hasn't broken down how the sales divide between platforms.
Sales for the zombie-slayer are set to jump again next month when the Left 4 Dead
survival addon gets freely released.
